Aircraft Noise Modeling

Aircraft noise modeling is primarily used for Airport Noise Compatibility Planning under Federal Aviation Regulation Part 150 and for Environmental Assessments and Environmental Impact Studies under Federal Aviation Administration Order 1050. 

Noise modeling is accomplished through the use of various computer programs which evaluate aircraft noise impacts around airports.  These noise modeling programs are based on a set of algorithms which estimate noise based upon several environmental factors.  Noise modeling evaluates noise output based upon either noise exposure, maximum noise levels or models may be time based.

Noise modeling is used to assess current aircraft noise impacts around airports or heliports, to assess changes in noise impacts resulting from new or extended runways or runway configurations, to evaluating noise impacts from new operational procedures and to assess noise impacts from new operational procedures.
